[The spatial organization of the cortical projection system of the nucleus accumbens in the canine brain].
The study was performed in 10 outbred dogs by method based on retrograde axonal transport of horseradish peroxidase. Spatial organization of cortical projection system was examined. The structure was shown to receive projections from meso- and allocortex. Neocortical projections were not found. Mesocortical ones from prelimbic, infralimbic, orbital, insular and cingular zones were demonstrated to extend throughout both segments of dog nucleus accumbens, while projections from allocortex (periamygdaloid and entorhinal cortical zones, as well as hippocampal formation subicular part) were found only in medial part of the structure studied. Thus, features of mediodorsal topography were discovered in organization of nucleus accumbens afferent cortical projection system, while rostrocaudal topography elements were not found. Cortical initial neurons projections to the dog nucleus accumbens are located multilaminarly.
